This Optibelt RB series belt is a Poly-V (multi-rib) belt with a PH profile and a length of 1309 mm. The profile and length are the two dimensions to match when selecting a replacement.
The PH profile identifies the rib pitch and cross-section of the belt, while 1309 mm gives the datum length around the pulley system. Both values must match the drive's original specification. Use them together when checking a belt against a parts list or a marking on an existing belt.
Poly-V belts transmit power through multiple small ribs that run in matching pulley grooves. The PH profile is a compact section used in light-duty, high-speed drives where a thin, flexible belt is needed. The 1309 mm length places this belt in a mid-range size for small-pulley equipment.
To request a quote, send the part number PH 1309 and the brand Optibelt. If you are replacing a belt on a drive, include the profile and length from the old belt's back marking, or send a photo of the marking. We carry Optibelt belts and can help confirm that this profile and length suit your application.

Frequently asked questions
- What do the PH profile and 1309 mm length mean for fit?
- The PH profile defines the rib geometry that must match the pulley grooves. The 1309 mm length is the datum length of the belt. Both must match the drive's specification for correct fit and tension.
- How do I confirm this is the right belt for my drive?
- Check the marking on the back of the old belt. It should show the profile and length. If it reads PH and 1309 mm, this belt matches those dimensions. If you cannot read the marking, measure the length and count the ribs, then send those details with your quote request.
- What information should I send with a quote request?
- Send the part number PH 1309 and the brand Optibelt. If you are matching an existing belt, also include the profile, length, and number of ribs from the old belt or a photo of its back marking. That helps us confirm the correct belt for your drive.
